Item 8 Determination of remuneration for new board member

The Nomination Committee proposes that the remuneration for the new member of the board of directors elected by the meeting shall be paid in accordance with the remuneration level decided at the 2025 annual general meeting (SEK 236 250) pro rata for the period from the date of the extraordinary general meeting, including any committee fees (SEK 50 000).

Item 9 Resolution to authorize the board of directors to resolve on new issues of shares, warrants, and/or convertibles

The shareholder Daniel S. Aegerter proposes that the extraordinary general meeting resolves to authorize the board of directors, for the period up until the next annual general meeting and on one or several occasions, with or without deviation from shareholders' preferential rights, to resolve on issues of new shares and on issues of warrants and/or convertibles with the right to subscribe/convert to shares. Such a resolution may be made with the condition that payment must be made in cash and/or by set-off and/or contribution in kind and/or combined with other terms. The number of shares that may be issued by virtue of this authorization whether as newly issued shares and/or upon exercise of warrants and/or conversion of convertibles, may not correspond to a dilution of more than 10 per cent of the total number of shares outstanding in the company immediately prior to the first utilization of the authorization, after full utilization of the proposed authorization.

The purpose of the authorization and, where applicable, the reason for the deviation from the shareholders' preferential right, is to provide flexibility for company acquisitions (including the use of shares and other financial instruments as consideration), to enable capital issues to facilitate expansion of the company's operations and for general corporate purposes.

The subscription price shall be determined in accordance with prevailing market conditions.

The board of directors or any person appointed by the board of directors shall be authorized to make such minor adjustments to this resolution that may prove necessary in connection with the registration of the resolution with the Swedish Companies Registration Office.

This resolution regarding authorization for the board of directors to resolve on issue of new shares, warrants and/or convertibles is valid if it has been supported by shareholders representing at least two thirds of both the votes cast and the shares represented at the extraordinary general meeting.
